Infrared curing process for touch panel manufacturing
First Claim
1. A method of processing a substrate for a touch panel utilizing infrared energy, said method comprising:
- providing an infrared energy source operable to emit infrared energy;
providing a glass substrate with a conductive thin film disposed on a surface of said glass substrate;
oxidizing said conductive thin film via operation of said infrared energy source to establish a transmissivity property of said conductive thin film for manufacturing of a touch panel;
bonding a thick film silver frit electrode pattern to said conductive thin film on said glass substrate via operation of said infrared energy source at the same time as oxidizing said conductive thin film is carried out; and
reducing said conductive thin film via operation of said infrared energy source.

Abstract
An infrared energy oxidizing and/or curing process includes an infrared oxidation zone having an infrared energy source operable to emit infrared energy that oxidizes a conductive thin film deposited or established on a glass substrate to establish a light transmissive or transparent conductive thin film for manufacturing of a touch panel. Optionally, the infrared energy curing process provides an in-line infrared energy curing process that oxidizes the conductive thin film on the glass substrate as the glass substrate is moved past the infrared energy source. Optionally, the infrared energy curing process bonds a thick film silver frit electrode pattern to the conductively coated glass substrate. Optionally, the infrared energy curing process reduces the transparent conductive thin film.
